Detonation Arresters

Detonation arresters are designed to prevent propagation of detonations in gas or vapour mixtures. Detonation flame arresters are specifically designed for pipelines with a significant distance between the ignition source and the arrester, or for use where the pipe is rough, bent, obstructed or has section changes.

Groth flame and detonation arresters are proven to inhibit flame propagation in gas piping systems and to protect liquid storage tanks containing vapors from gas groups C & D.
